The PAU is capable of operation in a WCDMA system. 1.2 (4) Type of Emission: F9W 1.3 (5) Frequency range: 869 to 894 MHz 1.4 (6) Range of Operating Power: The PAU is designed to supply a nominal power level of 44.5 dBm at the output connector which corresponds to 42.4 dBm in the Antenna Reference Point. 1.5 (7) Maximum Power Rating: The maximum power rating with one PAU under environmental and supply voltage variations is equal to 44.5 ±1 dBm which corresponds to 42.4 ±1 dBm in the Antenna Reference Point. 1.6 (8) Final Amplifier Voltage and Current In normal operation Average Output Power 44.5 dBm Values for Q2 and Q3 each Voltage 30.5 Volt DC Current 2.35 Ampere DC 1.7 (10) Frequency Stabilizing Circuit Description N.A. 1.8 (10) Spurious and Harmonic Suppression Spurious and harmonic suppression is achieved by using band pass filters in PAU. A filter module at the output (in PAU) works like a band pass filter around the carrier Ericsson Confidential LETTER 3 (3) Prepared (also subject responsible if other) No. EMWTHAN 2/0061-KRB 901 18/1 Uen Approved Checked Date Rev Reference EAB/PDB/RG [Thomas Andersson] 2005-10-18 A TA8AKRB90118-1 1.9 (10) Limiting Power The PAU measures the output power via an RF detector. The output will be switch off, if the power at the output connector exceeds 46.5 dBm. The PAU must be reset to switch on the output power again. 1.10 (10) Digital Modulation QPSK and 16QAM The PAU is intended for amplification of QPSK and 16QAM in a WCDMA system.

The Base Station Controller (BSC) remotely controls the maximum output power level. If the Power Amplifier Unit is not able to maintain the requirements for power output, frequency stability, etc an alarm is sent to the BSC. On severe faults the Power Amplifier Unit will disable transmission.

The sTRX ROJ 119 2288/1 WCDMA transceiver unit were used to generate the carrier channels. The measurements were done at the output connector (Ant A) of the single Antenna Interface Unit (sAIU) KRY 112 124/1. All measurements were performed at maximum output power with both modulations. A directional coupler were used the measure the input signal. Radiated measurements All radiated measurements were performed with the test object installed in a RBS 3303 cabinet powered with -48 VDC. The sTRX ROJ 119 2288/1 WCDMA transceiver unit were used to generate the carrier channels. The sTRX was activated for maximum transmit power. The sTRX was sequentially allocated to UARFCN 4357 (871.4 MHz), 4407 (881.4 MHz) and 4458 (891.6 MHz) for downlink and to UARFCN 4132 (826.4 MHz), 4182 (836.4 MHz) and 4233 (846.6 MHz) for uplink. Purpose of test The purpose of the tests is to verify compliance to the performance characteristics specified in FCC CFR 47.
